Make sure you are choosing a right target table in table comparison transform.

Also please remove record_id from compare column box.

Rest all the setting looks correct.

Try & let me know.

Thanks

Sure, your table is truncated before the data flow is started. All your input records will be new, when comparing to an empty table.

Just uncheck that option. Ignore all other answers to your post, your data flow logic is perfectly valid.
